Linear elastic fracture mechanics

2022
Abstract This chapter describes the asymptotic elastic crack tip solutions for stress and displacement fields, and the concept of stress intensity factors for Mode I, Mode II, and Mode III loadings. Since in most engineering applications globally brittle fracture of a structure occurs by crack propagation in a direction perpendicular to ...

Linear elastic fracture mechanics

2020
Abstract This chapter introduces the basics of linear elastic fracture mechanics. It starts by recalling the asymptotic elastic crack tip solutions and the concept of stress intensity factors for Mode-I, Mode-II, and Mode-III loading. The concept of critical stress intensity factor is next introduced as a model for fracture under small ...

Linear Elastic Fracture Mechanics

1997
The quantitative statements of the Griffith theory [1] are based on elasticity theory and are applicable only to those materials that obey Hooke’s law up to the instant of fracture. In confirming his theory, Griffith used glass as the test material because at room temperature glass does follow Hooke’s law to the stress at fracture. Griffith’s work must

Limits of Linear Elastic Fracture Mechanics

Journal of Pressure Vessel Technology, 1984
This paper presents a simple procedure for determining the validity limits of linear elastic fracture mechanics (LEFM) calculations for low alloy steel (ferritic) structures. The procedure is limited to structures with flaws whose depths are 50 percent or less of the wall thickness of the component at the flaw location and to components which can be ...

Fundamentals of Linear Elastic Fracture Mechanics

2021
Abstract The linear elastic fracture mechanics (LEFM) is the pillar of all fracture mechanics. In this chapter, it is presented in full, with complete derivations and many examples. Griffith's concept of the energy release rates is described, the elastic singular near-tip stress field is derived, and the stress intensity factors are ...

Linear elastic fracture mechanics

1989
In this and the following chapter, the fracture mechanics concepts for the analysis of fracture will be discussed. With these concepts it will be possible to obtain the residual strength diagram and the maximum permissible crack size (Chapter 1). Following the arguments used in Chapter 1, the discussion will be limited to mode I loading (mixed mode ...

Linear-Elastic Fracture Mechanics

2016
Solid bodies containing cracks can be characterized by defining a state of stress near a crack tip and the energy balance coupled with fracture. Introducing the Westergaard stress function and will allow the development of a significant stress analysis at the crack tip. These particular functions can be found elsewhere [12].
